Looks like a coup, smells like a coup but is not??????

Since Zimbabwe's independence in 1980, one man has ruled and his name is Robert Mugabe. Fast forward to today and the same man is now under house arrest by the military. But the military insists that this is not a coup or takeover. So what exactly is it?
